Blog secreto de matemática.
In this small and rather modest looking blog I want to post things that I think are interesting with as many details as I please. This means that most of what I write falls short from the formal treatments you can find on a textbook or a paper. This is fine. The other side of the coin is that I want it to be interesting and for that reason I want to include many examples and intuitions which I think is the comparative advantage an informal math blog has over a formal book.
